A man was struck around the face and fell to the floor before two thieves stole £300 from him, in Mildenhall.
Police have said the victim, a 40-year-old man, was walking back to his car, parked in Mill Street, after leaving Lloyds Bank where he had withdrawn the money from a cashpoint between 6.30 and 7pm on June 17.
He became aware of two men walking behind him and crossed the road. As he crossed one of the men shouted at him and he turned round. As he turned he was struck to the face with a large wooden object and fell to the ground.
Police said the two men stole the £300 from his hand and ran off down an alley way to the right of a Mill Street charity shop.
The alleyway leads to back of Mildenhall Job Centre where the men jumped over a fence.
The victim noticed a silver/grey Ford Mondeo drive past during the incident and police have appealed for the driver or passengers of this vehicle to come forward as they may be able to assist with the investigation.
Police have released a description of the men.
One man is described as black, approximately 5ft 8in tall, of extra-large build with a Nigerian-sounding accent. He was wearing a black hooded top with the hood up, a black and grey motocross scarf covering his mouth and black Nike trainers.
The second man is described as black, approximately 5ft 7in tall, of small to medium build with a British accent. He was wearing similar clothes to the first man and both are described as having short, straight fringes.
